Vascular Laboratory

NewYork-Presbyterian Lawrence Hospital's vascular surgeons maintain a state-of-the-art Vascular Laboratory — offering patients high-quality diagnostic studies and providing referring physicians with interpretations that assist their care of patients with vascular disease. All studies are performed by professional vascular technologists and interpreted by vascular surgeons.

Vascular Diagnostic Services

We offer a wide range of tests to evaluate symptoms, assess vascular function, and diagnose vascular disease, including:

  • Ankle brachial index (ABI) with pulse volume recordings (PVR). Doctors use these tests to measure blood flow and detect arterial blockages in the arms and legs. Together, these tests help determine the presence, severity, and location of peripheral arterial occlusive disease.
  • Aorta ultrasound scan. An aorta ultrasound exam can diagnose aneurysms that develop in the abdominal aorta, and is used to follow patients who have undergone aortic procedures.
  • Arterial duplex imaging. Using this high-frequency ultrasound test, vascular specialists can visualize arteries in the legs and the velocity and direction of blood flow in those arteries.
  • Carotid duplex. This ultrasound procedure can detect carotid artery disease — blood clots, plaque build-up, and other blood flow problems in the carotid arteries — early, before it causes any symptoms. When the disease is detected early, vascular specialists can perform procedures that are effective in preventing stroke.
  • Dialysis access evaluation. This ultrasound exam helps vascular specialists map veins and determine which can be used for hemodialysis access.
  • Digital photoplethysmography (PPG) with thermal measurement. Digital photoplethysmography (PPG) is an imaging test used to detect changes in blood flow at the microvascular level in the fingers and toes in people with Raynaud's disease.
  • Treadmill exercise testing for claudication. We use treadmill testing to detect peripheral artery disease in patients who have pain in their lower limbs (claudication). During a treadmill test, we can evaluate how exercise affects ankle-level blood pressure and analyze the relationship between claudication and vascular function.
  • Vein mapping for arterial bypass. Before performing surgery to perform a bypass, surgeons use preoperative ultrasound imaging to determine which vein segments might be used for bypass grafts.
  • Venous ultrasound scan of the upper and lower extremities. This ultrasound exam shows blood flowing through blood vessels and can be used to detect deep vein thrombosis (DVT) and superficial vein thrombosis (SVT).
